Today we were highlighted on the BYU homepage with a video made by BYU broadcasting about rock skipping. The video highlights two methods of skipping stones and our recent work with the Waboba-water bouncing ball. The Daily Herald joined us while we were filming at Utah Lake in May. The article by James Roh gives a [...]
When a ball is dropped into a puddle, momentum is exchanged between the impacting ball and the surrounding fluid, decreasing the rebound height. At impact, a radial jet and splash curtain are formed as fluid is instantaneously displaced by the falling ball. During rebound, the splash curtain is drawn in and a column of fluid [...]
When a buoyant rising sphere exits the free surface there are several angles of trajectory and heights observed. Children experience this when playing with a ball while swimming. The pop up height and direction of trajectory above the free surface are dependent on the release depth of the sphere below the free surface. The release [...]
Some of our Waboba/Skipping Stone research made its way to the MIT Technology Review and to the New Scientist!
Some of our work on 3D imaging of flames was featured on Science Friday and BYU Radio Below is the video from the Science Friday piece.
Some of the media coverage about APS in November 2009: On Feb 2, 2010, the poster we presented at APS was highlighted in National Geographic. BYU also highlighted our submissions for APS in an article on their homepage. Kate Arneman wrote a full page introduction to the annual APS-DFD Gallery of Fluid Motion, entitled Fluid Fantastica, which was [...]
I was very excited to visit the set of Time Warp last April and talk about the work I did as a PhD student. I haven’t posted the event until now because I thought it would be better to post a clip from the show. I tried to get the producer to send me free [...]
On TV: Tadd Truscott and Alex Techet show how bullets can enter the water on the Discovery Channel “Time Warp” starting Wednesday Nov. 19th 8:30 pm Episode: Breakdancing (11/2008).
Previous studies have shown that applying a hydrophobic coating to one-half of a hydrophilic sphere will cause asymmetric cavity formation and a deflection in the trajectory of a sphere. Half of an axisymmetric projectile will be coated with the hydrophobic coating and dropped in a similar manner to determine if there is similar asymmetric cavity [...]
When the conditions are right, a solid sphere can pass through a soap bubble without rupturing the soap film. As the sphere passes through the soap film, a pinch-off occurs and the soap film reseals itself. Predicting whether or not a soap film will rupture is dependent upon the speed [...]
